Power Box is a U.S.-based engineering and manufacturing company located in Connecticut, owned and operated by David and Paul Christian. With over 40 years of experience designing and manufacturing effects pedals and guitar-centric products, David and Paul bring deep technical expertise and real-world musician insight to every product they create.

Over the course of their careers, they have been awarded multiple mechanical and electrical patents and have provided OEM design and manufacturing services for leading MI brands including Gibson and Fender. They have also developed several proprietary products, including Big Joe–branded effects pedals and the legendary Pocket Rock-It headphone amplifier that helped launch their career.

Power Box ISO rechargeable battery power supplies are their latest innovation. Designed and manufactured in the USA, these power systems feature patented BiWire™ isolation technology and ultra-clean, rechargeable DC power. Each output is fully electrically isolated while drawing from a single internal battery source. Intelligent internal power management continuously monitors battery status and delivers the precise current required by each pedal on your board.

The result is a modern, efficient, and noise-free way to power virtually any pedalboard.
